Struct Storage 

pub struct Storage { /* private fields */ }

Synchronous, file-backed cache.

Implementations

impl Storage

pub fn new() -> Result<Self>

Create a Storage resolving the cache dir exactly like the JS: honor ~/.tse tracker file if present, else default to ~/tse-cache.

pub fn with_dir<P: AsRef<Path>>(dir: P) -> Result<Self>

Create a Storage rooted at an explicit directory (useful for tests).

pub fn cache_dir(&self) -> &Path

The current cache directory (JS CACHE_DIR).

pub fn get_item(&self, key: &str) -> Result<String>

Read a value, creating an empty file if missing (JS getItem).

pub fn set_item(&self, key: &str, value: &str) -> Result<()>

Write a value (JS setItem).

pub fn get_item_async(&self, key: &str, zip: bool) -> Result<String>

Async-equivalent read (JS getItemAsync). Optionally gunzips.

pub fn set_item_async(&self, key: &str, value: &str, zip: bool) -> Result<()>

Async-equivalent write (JS setItemAsync). Optionally gzips.

pub fn get_items( &self, selins: &HashSet<String>, result: &mut HashMap<String, String>, ) -> Result<()>

Load the cached price CSVs for the selected instruments (JS getItems). Only the requested inscodes are read into result.

pub fn itd_get_items( &self, selins: &HashSet<String>, full: bool, ) -> Result<HashMap<String, HashMap<String, ItdValue>>>

Intraday: read stored devens for selected instruments (JS itd.getItems). When full is true, the gzipped bytes are returned; otherwise each deven maps to an empty marker (presence only).

pub fn itd_set_item( &self, key: &str, obj: &HashMap<String, ItdValue>, ) -> Result<()>

Intraday: write one instrument’s deven map (JS itd.setItem). Values equal to “N/A” are stored uncompressed; everything else gzipped.

Trait Implementations

impl Clone for Storage

fn clone(&self) -> Storage

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Storage

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
